The SUR-FIT Natura® Two-Piece Ostomy System is ConvaTec’s most extensive two-piece product line. The SUR-FIT Natura® Flange System signals a secure, accurate closure with a series of audible “clicks”. A simple snap-off, snap on design allows users to change the pouch quickly to match activities without removing the skin barrier from the skin. Durahesive® skin barriers are designed for people whose stoma output is mostly liquid. Unlike other skin barriers that can break down around liquid output, Durahesive® skin barriers swell up to protect the stoma. This special effect, called turtlenecking, helps create a more secure seal without harming the skin. ConvaTec Moldable Technology™ skin barriers provided a personalized, custom fit around the stoma to help protect the peristomal skin. They require no cutting or guess work making them very easy to use.
